Some Nivea spray. Can't remember the name now...

Something like "Black Tentation" or "Dark Seduction" ????

You know the usual BS name they give to their sprays.

But it has nothing to do with that specific deodorant anyway.

Look it up on the internet.

You'll see it's a very common issue when wearing white t-shirts.

just wondering since I've never had the issue, you might as well try switching deodorants to see if that fixes the problem 

my accountant had black stained armpits so your lucky only yellow .it can only get worse

In the future buy yellow t-shirts ????

 

Vanish O2 stain remover. Rub it into the stain, soak for an hour, warm wash. Worked for me.
